Answer;
Complementary base pairs;
- Adenine-Thyamine and Guanine-Cytosine (A-T and G-C)
Explanation;
-According to Chargaf's rule, the secondary structure of the DNA requires that every guanine pairs with a cytosine and every thymine pairs with an adenine, resulting in consistent ratios between the nucleotides.
-In double-stranded DNA, two long molecules twist around one another in a double helix. Pairs of nitrogenous bases are set in the same plane, and interact with each other via hydrogen bonding. These pairs are often referred to as base pairs

Answer:Domain is the Answer
Explanation:
The answer is: B - archaea
Explanation:
The organisms found in the subtropical forests of southern China which were acid tolerant and lacked internal organelles are the Archaea. Archaea refers to the domain of life with organisms living in extreme conditions. Because of this, the Archaea are referred to as the extremophiles.
The cells are very small, prokaryotic and are similar to bacteria in lacking a nucleus and membrane bound organelles. The cell membrane is bounded by a cell wall. They reproduce by binary fission, fragmentation or budding.
They can tolerate high temperatures and survive in hot springs, anaerobic conditions and are acid-tolerant. These acid tolearting Archaea are called the acidophiles surviving in a pH of 2 or less than 2.
They pump out protons out of the intracellular space and thus keep their cytoplasm in a neutral pH or have an acidified cytoplasm. The example are Thiobacillus acidophilus, Crenarchaeota and others.
Answer:
Anaerobic chemoorganotrophy.
Explanation:
Anaerobic chemoorganotrophs may be defined as the organisms that has the ability to prepare their food with the help of organic chemicals in the basence of oxygen. The microorganism uses this metabolism to cause disease in other organism.
The pathogens like Clostridium tetani use the anaerobic chemoorganotrophs bacteria as they injected into the tissue and do metabolism without the presence of oxygen. They can not cause disease on skin surface as abundant oxygen is present on the body surface.
Thus, the answer is anaerobic chemoorganotrophy.
